[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 5 As shown, a cone-connected column porcelain insulator includes a ceramic body 1 and a support plate seat 8. An insulating rubber pad 2 is provided directly above the ceramic body 1, and a cap accessory 3 is provided directly above the insulating rubber pad 2. An adjustment mechanism 5 is provided directly below the ceramic body 1. The adjustment mechanism 5 adjusts the installation angle of the bottom end of the ceramic body 1 according to the installation position of the ceramic body 1. A positioning mechanism 15 is provided on the outside of the support plate seat 8. The support plate seat 8 unfolds the connecting parts on the outside of the support plate seat 8 according to the administration of the installation position, thereby improving the stability of the support plate seat 8 during the installation process.

[0023] In this embodiment, the adjustment mechanism 5 includes a base 4, a fastening hole 6, a semicircular fastening seat 7, a metal rod 9, a rolling bearing 10 and a fastener 11. The base 4 is arranged at the bottom end of the metal rod 9, and the metal rod 9 is connected to the interior of the ceramic body 1. The outer side of the semicircular fastening seat 7 is connected to the base 4, and the outer side of the base 4 is connected to the fastener 11. The outer side of the semicircular fastening seat 7 is provided with fastening holes 6 at equal intervals, and the rolling bearing 10 is installed inside the base 4.

[0024] In this embodiment, the metal rod 9 is connected to the inside of the base 4 via a rolling bearing 10 connected to the bottom end. The metal rod 9 set on the top end of the rolling bearing 10 is rotated to adjust and control the connection of the cap accessory 3.

[0025] In this embodiment, the positioning mechanism 15 includes a pallet seat 8, an isolation gasket 12, a bottom clamping strip 13 and a bearing shaft 14. The pallet seat 8 is installed at the bottom end of the semicircular fastening seat 7. The bottom clamping strip 13 is symmetrically arranged at the bottom end of the pallet seat 8. The outer side of the bottom clamping strip 13 is connected with the bearing shaft 14. The outer side of the bottom clamping strip 13 is connected with an isolation gasket 12. The bottom clamping strip 13 is used to increase the clamping force of the bottom end of the pallet seat 8 to avoid the connection structure of the pallet seat 8 being too simple.

[0026] In this embodiment, the support plate seat 8 is connected to one end of the bottom clamping bar 13 through a through-connected bearing shaft 14, and the bottom clamping bar 13 and the support plate seat 8 are rotated to adjust the positioning of the bottom clamping bar 13.

[0027] In this embodiment, the base 4 is connected to the semicircular fastening seat 7 through a fastener 11 that penetrates the base 4 on one side. The base 4 and the semicircular fastening seat 7 are tilted and adjusted to meet the adjustment control of the base 4.

[0028] The practical application of this cone-connected column porcelain insulator includes the following work contents:

[0029] Step 1: The operator first contacts the pallet seat 8 with the building or cable rack according to the use requirements, and pulls the bottom clamping strip 13 to rotate the bottom clamping strip 13 on the outside of the pallet seat 8, so that the clamping angle formed by the bottom clamping strip 13 and the pallet seat 8 clamps and positions the outside of the building frame, and locks the bottom clamping strip 13 and the outside of the building frame with bolts, thereby completing the positioning of the pallet seat 8 and improving the stability of the pallet seat 8 during the high-altitude positioning process. The isolation gasket 12 provided on the outside of the bottom clamping strip 13 contacts the iron frame to increase the friction force of the connection of the bottom clamping strip 13;

[0030] Step 2: The operator can install the base 4 on the surface of the semicircular fastening seat 7, and then adjust the angle of the semicircular fastening seat 7 and the ceramic body 1, and then insert the fastener 11 horizontally into the inside of the fastening hole 6, and fasten the outside of the base 4 and the semicircular fastening seat 7 to complete the angle positioning of the ceramic body 1. After installing the insulator, connect the cable and the equipment to the cap fitting 3 set at the top of the ceramic body 1. When connecting the cable, ensure that all connections are tight and seamless, and have good contact;

[0031] Step 3: During installation, the insulating rubber pad 2 supports and isolates the bottom end of the cap accessory 3. According to the position of the wire and the ceramic body 1, the metal rod 9 set on the outside of the ceramic body 1 can be pulled, so that the rolling bearing 10 set at the bottom end of the metal rod 9 inside the ceramic body 1 rotates on the outside of the base 4, and then the installation direction of the cap accessory 3 set at the top of the metal rod 9 is adjusted.

[0032] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
